I always like to start with the basics...
Injector timing set dead-on or somewhat ahead.
Cam timing verified
Valve lash checked.
Glows verified good... ie they get red.
Short of this, it sounds a lot like poor compression. And across all
cylinders at that. How many miles/km on the engine?

> He said to spray a few squirts of WD40 into the air intake after the filter (so the filter didn't absorb it), then try starting it, it should start right away from the fumes since WD40 is petroleum based, he said it bypasses the pump through the air intake, and should tell you if the pump is bad if it starts.(apparently people use it for cold starting caterpillars etc. evn works if glow plug system is bad.
